[Feature request] Option to load image sorted by modified date

[KevCui]

Using ucollage to open all images in a folder, the current behavior is to load all images sorted alphabetically by file name. It would be great to have another option to sort files by modified date, the most recent modified one showing at the first place.

We could do something like

filelist=($(ls -c "$@"))

@KevCui Do you want to work on this?

@ckardaris Sure, I'll try, but not promise that it will be done soon 🙂

Ok, we should have an exported variable UCOLLAGE_SORT with accepted values {name, time and anything else}
You should modify the README at the end and the relevant parts in functions parse_config and set_defaults
